Thanks! Will give it a try a bit later.

(HN algorithms have killed some of your comments, perhaps because you posted the same URL too many times from a relatively new account? I’ve vouched for you, but keep in mind that it triggers antispam.)

Edit: naturally, no luck:

  $ ./exploit /system/bin/ping
  [+] target:    /system/bin/ping

  socket(AF_ALG): Permission denied

Guess AF_ALG is just disabled on Android kernel builds. Though maybe it’ll work on other devices!
